More DLC in L.A. Noire's future

According to this Kotaku article, Rockstar is not finished with their hit detective sim, L.A. Noire. When asked if Reefer Madness was the end of new content for L.A. Noire, Rockstar told Kotaku that it wasn't. They offered no hints as to whether they were planning just more suits and weapons, a full Undead Nightmare-style expansion, or some combination thereof, however. Anyone who has played L.A. Noire to at least the homicide desk, knows that Cole Phelps spent months working the burglary desk before his promotion to homicide, and that that period in Cole's career was missing completely from the game. That surely seems like a probable starting point for any major expansion to the game. For me personally, they're going to have to do more than offer suits and guns to draw me back to L.A. Noire.
